This is a classic misunderstanding of the gospel and of Christian theology. By this logic you lose your salvation every time you sin. Read up on the doctrine of justification, read the book of hebrews. Sacrifice is offered once for all sins. No one is sent to hell for specific sins. The bible teaches that humanity inherited a sin nature from adam (romans 5) and is born spiritually dead and will reap that inheritance, namely hell. (ephesians 2, John 3) There is no single sin that condemns, all are born condemned and the sins we commit are fruit of that sinful nature. This is why Jesus says 'you must be born again'. That happens once, no need to be born again every time you continue to sin after.
